Answer 2

Resposta:

Explicação passo-a-passo:

a)-10 - (-7) - 1 =

= -10+7-1

=-3-1

= -4

b) 25- (- 6)-(-8)

= 25+6+8

= 25+14

= 39

c) - 12-(1)- 6 =

= -12-1-6

= -19

d) -(+9)-4-11=

= -9-15

= - 24

e) - 35 + (-5) + 30

= -35-5+30

= -40+30

= -10

f) – 80 – (+ 9) - 42 =

= -80-9-42

= -80-51

= -131

g) 26– (+8)+(-10) =

= 26-8-10

= 26-18

= 8

h)-22-(+8)-(-10)=

= - 22-8+10

= -30+10

= - 20

i)- 20 + (20) - (+20)

= -20+20-20

= -20
